Air pollution can affect how well we sleep, scientists discover
The article discusses the findings of a global metastudy that suggests air pollution can affect sleep quality and duration. The study, led by Dr. Junxin Li of the Johns Hopkins University School of Nursing, examined 25 high-quality studies involving over 1.2 million people in six countries, including China, India, the US, and Germany. The researchers found that long-term exposure to air pollutants is linked to shorter or lower-quality sleep, particularly in older adults. The study was inspired by Li's previous research in the Baltimore area, where they noticed that outdoor air quality and nearby traffic fumes may be influencing the sleep of older residents. The article highlights the growing body of evidence suggesting that the air we breathe, both indoors and outdoors, can have a significant impact on our sleep patterns and overall health.
